Pressure vessel cylinder body pairing machine and its use method

Abstract

The invention discloses a barrel assembling machine for a pressure container and an application method of the barrel assembling machine. The barrel assembling machine comprises an assembling machine frame, wherein I-beams are arranged on the left side and the right side of the assembling machine frame; a plurality of barrel assembling devices which are symmetrically arranged on the assembling machine frame; each barrel assembling device comprises an oilcylinder, a lug base and a pressure plate; the oil cylinders are hinged to the pressure plate through the lug bases; a piston rod of each oil cylinder is capable of pushing the corresponding pressure plate to the center of the assembling machine frame; each pressure plate is a V-shaped plate with a concave middle; the V-shaped plates face the center of the assembling machine frame; the assembling machine frame is also provided with a lifting device; the lifting device comprises a motor, an elevator, a screw rod and a frame guide post; the frame guide post is fixedly arranged; the motor is connected with the elevator; one end of the screw rod is connected with the elevator and the other end of the screw rod is propped against the assembling machine frame; the elevator can control the screw rod to vertically displace under the drive of the motor; the assembling machine frame can be vertically arranged on a limiting rod in a sliding manner. The barrel assembling machine has the advantages of being convenient to assemble, high in efficiency and low in work difficulty, and is capable of ensuring the assembling accuracy.

Description

technical field [0001] The invention relates to the technical field of butt welding of cylinder bodies, in particular to a pressure vessel cylinder body assembly machine and a use method thereof. Background technique [0002] Metal pressure vessels are widely used in chemical industry, petroleum, machinery, metallurgy, nuclear energy, aerospace and other departments, and are indispensable equipment in the production process. At present, the known way of assembling the cylinders of pressure vessels is to use point-by-point mechanical butt welding to the cylinders by using wedges, jacks and the like. This method has a number of disadvantages. For example, butt-welding of tooling (wedges) is mainly carried out manually in the butt-welding group of the barrel group, which is difficult, low in efficiency, high in cost, and poor in safety. [0003] Another disadvantage of the above-mentioned method is that after the completion of the cylinder assembly, it is necessary to grind t...

Problems solved by technology

For example, the butt welding of tooling (wedge) is mainly carried out manually in the butt welding group of the cylinder group, which is difficult, low in efficiency, high in cost and poor in safety.

[0003] Another disadvantage of the above method is that after the completion of the cylinder assembly, it is necessary to grind the process solder joints of the welding assembly tooling, which seriously affects the welding appearance quality of the pressure vessel.
